Serving Silicon Valley and being in the most efficiency-centric state in the country have made Pacific Gas & Electric take the lead on data center efficiency.

Data centers make up about 2.5% of PG&E's load and that's expected to grow dramatically. The load is about 400-500 mw now and 50-75 mw is coming online in the next 12-18 months, Principal Program Manager for PG&E's customer energy efficiency Mark Bramfitt told us.

The utility revealed other proposals in the last couple of weeks, too - one for a 60 mw data center in San Jose and a proposal to put data centers on barges and have them anchored in San Francisco Bay.

PG&E used its experience dealing with large data centers loads to draw 24 utilities from across the U.S. and Canada at the Utility IT Energy Efficiency Conference recently.

It's not just high-tech firms such as E-Bay or Hewlett Packard that have data centers but firms such as Bank of America with a large facility in San Francisco.

The "dot-com" era saw a huge build-out in data centers but that storage space was largely used-up and another growth spurt is underway.

Normal businesses including PG&E are using the technology and their growth rates are 10-20% but data center load is growing twice that fast at high-tech firms.

People are also keeping data for far longer than they used to in order to comply with regulations such as Sarbanes-Oxley.

The EPA estimated that the energy use at data centers doubled in the last five-years and is set to repeat that over the next five.

Both existing and new data centers have lots of opportunities to cut down on their power use, said Bramfitt.

"Our programs are pushing a number of technologies. The big hitters are using outside air for cooling because our climate is quite moderate," he added.

"So instead of running your air-conditioner 24-7, you can use outside air when it's cool enough."

PG&E is pushing virtualization and consolidation to help customers use dramatically fewer computer servers.

High efficiency UPS systems, air flow management and other opportunities can be used to trim down power use at data centers, too.

"We think in most existing data centers you can cut a third to a half of the energy usage with cost effective technologies," said Bramfitt.

PG&E works with customers building new data centers to help them improve efficiency up to 10%.

The program's Bramfitt runs saved three or four mw last year and he means to grow them to 15 mw to 25 mw - but the growth rate in data center use means that won't "make much of a dent."

Florida Court Blocks Push to Break Electricity Monopolies

Florida Electricity Deregulation Ruling highlights the Florida Supreme Court decision blocking a ballot measure on retail choice, preserving utility monopolies for NextEra and Duke Energy, while similar deregulation efforts arise in Virginia and Arizona.

 

Key Points

A high court decision removing a retail choice ballot measure, keeping Florida utility monopolies intact for incumbents.

✅ Petition language deemed misleading for 2020 ballot

✅ Preserves NextEra and Duke Energy market dominance

✅ Similar retail choice pushes in VA and AZ

 

Florida’s top court ruled against a proposed constitutional amendment that would have allowed customers to pick their electricity provider, even as Florida solar incentives face rejection by state leaders, threatening monopolies held by utilities such as NextEra Energy Inc. and Duke Energy Corp.

In a ruling Thursday, the court said the petition’s language is “misleading” and doesn’t comply with requirements to be included on the 2020 ballot, reflecting debates over electricity pricing changes at the federal level. The measure’s sponsor, Citizens for Energy Choice, said the move ends the initiative, even as electricity future advocacy continues nationwide.

“While we were confident in our plan to gather the remaining signatures required, we cannot overcome this last obstacle,” the group’s chair, Alex Patton, noting ongoing energy freedom in the South efforts, said in a statement.

The proposed measure was one of several efforts underway to deregulate U.S. electricity markets, including New York’s review of retail energy markets this year. Earlier this week, two Virginia state lawmakers unveiled a bill to allow residents and businesses to pick their electricity provider, threatening Dominion Energy Inc.’s longstanding local monopoly. And in Arizona, where Arizona Public Service Co. has long reigned, regulators are considering a similar move, while in New England Hydro-Quebec’s export bid has been energized by a court decision.

Volkswagen has indicated that it will work on providing support and retraining opportunities for affected employees, as the EV aftermarket evolves and reshapes service needs, but the transition will still pose challenges for workers and their communities.

Environmentally, the shift towards electric vehicles represents a significant positive development. Electric vehicles produce zero tailpipe emissions, which aligns with global efforts to combat climate change and reduce air pollution. By focusing on EV production, Volkswagen is contributing to the reduction of greenhouse gas emissions and supporting the transition to a more sustainable transportation system.

Challenges and Opportunities

While the transition to electric vehicles presents opportunities, it also comes with challenges. Volkswagen will need to manage the complexities of closing and repurposing its existing plants while ramping up production at new or upgraded facilities dedicated to EVs. This transition requires substantial investment in new technologies, infrastructure, and training, including battery supply strategies that influence manufacturing footprints, to ensure a smooth shift from traditional automotive manufacturing.

Additionally, Volkswagen faces competition from other automakers that are also investing heavily in electric vehicles, including Daimler's electrification plan outlining the scope of its transition. To maintain its competitive edge, VW must continue to innovate and offer attractive, high-performance electric models that meet consumer expectations.

Future Outlook

Looking ahead, Volkswagen’s focus on electric vehicles aligns with broader industry trends and regulatory pressures. Governments worldwide are implementing stricter emissions regulations and providing incentives for EV adoption, although Germany's plan to end EV subsidies has sparked debate domestically, creating a favorable environment for companies that are committed to sustainability and clean technology.

Volkswagen’s investment in electric vehicles and its strategic realignment reflect a proactive approach to addressing these trends. The company’s ability to navigate the challenges associated with plant closures and the transition to electric mobility will be critical, especially as Europe's EV slump tests demand signals, in determining its success in the evolving automotive landscape.

Conclusion

Volkswagen’s decision to close several plants in Germany and focus on electric vehicle production represents a significant shift in the company’s strategy. While the closures present challenges, they also highlight Volkswagen’s commitment to sustainability and its response to the growing demand for cleaner transportation solutions. By investing in electric vehicles and adapting its operations, Volkswagen aims to lead the way in the transition to a more sustainable automotive future. As the company moves forward, its ability to effectively manage this transition will be crucial in shaping its role in the global automotive market.

B.C. Commercial electricity consumption plummets during COVID-19 pandemic

BC Hydro COVID-19 Relief Fund enables small businesses to waive electricity bills for commercial properties during the pandemic, offering credits, rate support, and applications for eligible customers forced to temporarily close.

 

Key Points

A program that lets eligible small businesses waive up to three months of BC Hydro bills during COVID-19 closures.

✅ Eligible small general service BC Hydro accounts

✅ Up to 3 months of waived electricity charges

✅ Must be temporarily closed due to the pandemic

 

Businesses are taking advantage of a BC Hydro relief fund that allows electricity bills for commercial properties to be waived during the COVID-19 pandemic.

More than 3,000 applications have already been filed since the program launched on Wednesday, allowing commercial properties forced to shutter during the crisis to waive the expense for up to three months, while Ontario rate reductions are taking effect for businesses under separate measures. 

“To be eligible for the COVID-19 Relief Fund, business customers must be on BC Hydro’s small general service rate and have temporarily closed or ceased operation due to the COVID-19 pandemic,” BC Hydro said in a statement. “BC Hydro estimates that around 40,000 small businesses in the province will be eligible for the program.”

The program builds off a similar initiative BC Hydro launched last week for residential customers who have lost employment or income because of COVID-19, and parallels Ontario's subsidized hydro plan introduced to support ratepayers. So far, 57,000 B.C. residents have applied for the relief fund, which amounts to an estimated $16 million in credits, amid scrutiny over deferred BC Hydro operating costs reported by the auditor general.

Electricity use across B.C. has plummeted since the outbreak began. 

According to BC Hydro, daily consumption has fallen 13% in the first two weeks of April, aligning with electricity demand down 10% reports, compared to the three-year average for the same time period.

Electricity use has fallen 30% for recreation facilities, 29% in the restaurant sector and 27% in hotels, while industry groups such as Canadian Manufacturers & Exporters have supported steps to reduce prices.

Elizabeth May wants a fully renewable electricity grid by 2030. Is that possible?

Green Party Mission Possible 2030 outlines a rapid transition to renewable energy, electric vehicles, carbon pricing, and grid modernization, phasing out oil and gas while creating green jobs, public transit upgrades, and building retrofits.

 

Key Points

A Canadian climate roadmap to decarbonize by 2030 via renewables, EVs, carbon pricing, and grid upgrades.

✅ Ban on new gas cars by 2030; accelerate EV adoption and charging.

✅ 100 percent renewable-powered grid with interprovincial links.

✅ Just transition: retraining, green jobs, and building retrofits.

 

Green Party Leader Elizabeth May has a vision for Canada in 2030. In 11 years, all new cars will be electric. A national ban will prohibit anyone from buying a gas-powered vehicle. No matter where you live, charging stations will make driving long distances easy and affordable. Alberta’s oil industry will be on the way out, replaced by jobs in sectors such as urban farming, renewable energy and retrofitting buildings for energy efficiency. The electric grid will be powered by 100 per cent renewable energy as Canada’s race to net-zero accelerates.

It’s all part of the Greens’ “Mission Possible” – a detailed plan released Monday with a level of ambition made clear by its very name. May insists it’s the only way to confront the climate crisis head-on before it’s too late.

“We have to set our targets on what needs to be done. You can’t negotiate with physics,” May told CTV’s Power Play on Monday.

But is that 2030 vision realistic?

CTVNews.ca spoke with experts in economics, political policy, renewable energy and climate science to explore how feasible May’s plan is, how much it would cost and what transitioning to an environmentally-centred economy would look like for everyday Canadians.

 

MOVING TO A GREEN ECONOMY

Recent polling from Nanos Research shows that the environment and climate change is the top issue among voters this election.

If the Greens win a majority on Oct. 21 – an outcome that May herself acknowledged isn’t likely – it would signal a major restructuring of the Canadian economy.

According to the party’s platform, jobs in the fuels sectors, such as oil and gas production in Alberta, would eventually disappear. The Greens say those job losses would be replaced by opportunities in a variety of fields including renewable energy, farming, public transportation, manufacturing, construction and information technology.

The party would also introduce a guaranteed livable income and greater support for technical and educational training to help workers transition to new jobs.

But Jean-Thomas Bernard, an economist who specializes in energy markets, said plenty of people in today’s energy sector, such as oil and gas workers, wouldn’t have the skills to make that transition.

“Quite a few of these jobs have low technical requirements. Driving a truck is driving a truck. So quite few of these people will not have the capacity to be recycled into well-paid jobs in the renewable sector,” he said.

“Maybe this would be for the young generation, but not people who are 40, 45, 50.”

Ryan Katz-Rosene is an associate professor at the University of Ottawa who researches environmental policy. He says May’s overall pitch is technically possible but would require a huge amount of enthusiasm on behalf of the public. 

“The plan in itself is not physically impossible. It is theoretically achievable. But it would require a major, major change in the urgency and the level of action, the level of investment, the level of popular urgency, the level of political commitment,” he said.

“But it’s not completely fantastical in it being theoretically impossible.”

 

PHASING OUT BITUMEN PRODUCTION

Katz-Rosene said that, under the Greens’ plan, Canadians would need to pay for a bold carbon pricing plan that helps shift the country away from fossil fuels and has significant implications for electricity grids, he said. It would also mean dramatically upscaling the capacity of Canada’s existing electrical grid to account for millions of new electric cars, reflecting the need for more electricity to hit net-zero as demand grows.

 “Given Canada’s slow attempt to climate action and pretty lacklustre results in these years, to be frank, this plan is very, very difficult to achieve. We’re talking 11 years from now. But things change, people change, and sometimes that change can occur very quickly. Just look at the type of climate mobilization we’re seen among young people in the last year, or the last five years.”

Bernard, the economist, is less optimistic. He cited international agreements such as the Kyoto Protocol from 1997 and the more recent Paris Climate Agreement and said that little has come of those plans.

A climate solution with teeth, he suggests, would need to be global – something that no federal government can completely control.

“I find a lot this talk to be overly optimistic. I don’t know why we keep having this talk that is overly optimistic,” he said, adding that he believes humankind is already beyond the point of being able to stop irreversible climate change. 

“I think we are moving toward a mess, but the effort to control that is still not there.”

As for transitioning away from Canada’s oil industry, Bernard said May’s plan simply wouldn’t work.

“Trying to block some oil production here and there means more oil will be produced elsewhere,” he said. “Canada could become a clean country, but worldwide it would not be much.”

Mike Hudema, a climate organizer with Greenpeace Canada, thinks the Green Party’s promises for 2030 are big – and that’s kind of the point.

“They are definitely ambitious, but ambition is exactly what these times call for.  Unfortunately our government has delayed acting on this problem for so long that we have a very short timeline which we have to turn the ship,” he said.

“So this is the type of ambition that the science is calling for. So yes, I believe that if we here in Canada were to put our minds to addressing this problem, then we have the ability to reach it in that 2030 timeframe.”

In a statement to CTVNews.ca, a Green Party spokesperson said the 2030 timeline is intended to meet the 45 per cent reduction in emissions by 2030 as laid out by the Intergovernmental Panel on Climate Change.

“If we miss the 2030 target, we risk triggering runaway global warming,” the spokesperson said.

 

GREENING THE GRID BY 2030

Greening Canada’s existing electric grid – a goal May has pegged to 2030 – is quite feasible, Katz-Rosene said, and cleaning up Canada’s electricity is critical to meeting climate pledges. Already, 82 per cent of the country’s electric grid is run off of renewable resources, which makes Canada a world leader in the field, he said.

Hudema agrees.

“It is feasible. Canada does have a grid already that has a lot of renewables in it. So yes we can definitely make it over the hump and complete the transition. But we do need investments in our electric grid infrastructure to ensure a certain capability. That comes with tremendous job growth. That’s the exciting part that people keep missing,” Hudema said.

But Bernard said switching the grid to 100 per cent renewables would be quite difficult. He suggested that the Greens’ 2030 vision would require Ontario and Quebec’s hydro production to help power the Prairies.

“To think we could boost (hydro production) much more in order to meet Saskatchewan and Alberta’s needs? Oh boy. To do this before 2030? I think that’s not reasonable, not feasible.”

In a statement to CTV News, the Greens said their strategy includes building new connections between eastern Manitoba and western Ontario to transmit clean energy. They would also upgrade existing connections between New Brunswick and Nova Scotia and between B.C. and Alberta to boost reliability.

A number of “micro-grids” in local communities capable of storing clean energy would help reduce the dependency on nationwide distribution systems, the party said.

Even so, the Greens acknowledged that, by 2030, some towns and cities will still be using some fossil fuels, and that even by 2050 – the goal for achieving overall carbon neutrality – some “legacy users” of fossil fuels will remain.

However, according to party projections, the emissions of these “legacy users” would be at most 8 per cent of today’s levels and those emissions would be “more than completely offset” by re-forestation and new technologies, such as CO2 capture and storage.

 

ELECTRIC VEHICLE REVOLUTION

The Green Party’s platform promises to revolutionize the Canadian auto sector. By 2030, all new cars made in Canada would be electric and federal EV sales regulations would prohibit the sale of cars powered by gasoline.

Danny Harvey, a geography professor with the University of Toronto who specializes in renewable energy, said he thinks May’s plan for making a 100 per cent renewable-powered electric grid is feasible.

On cars, however, he thinks the emphasis on electric vehicles is “misplaced.”

“At this point in time we should be requiring automobiles to transition, by 2030, to making cars that can go three times further on a litre of gasoline than at present. This would require selling only advanced hybrid-electric vehicles (HEVs), which would run entirely on gasoline (like current HEVs),” he said.

“After that, and when the grid is fully ready, we could make the transition to fully electric or plugin hybrid electric vehicles, possibly using H2 for long-distance driving.”

At the moment, zero-emissions vehicles account for just over 2 per cent of annual vehicle sales in Canada. Katz-Rosene said that “isn’t a whole lot,” but the industry is on an exponential growth curve that doesn’t show any signs of slowing.

The trouble with May’s 2030 goal on electric vehicles, he said, has to do with Canadians’ taste in vehicles. In short: Canadians like trucks.

“The biggest obstacle I see is that I don’t even think it’s possible to get a light-duty truck, a Ford F150, in an electric model in Canada. And that’s the most popular type of vehicle,” he said.

However, if a zero emissions truck were on the market – something that automakers are already working on – then that could potentially shake things up, especially if the government introduces incentives for electric vehicles and higher taxes on gasoline, he said.

 

WHAT ABOUT THE COST?

CTVNews.ca reached out to the Green Party to ask how it would pay to revamp the electrical grid. The party did not give a precise figure but said that the plan “has been estimated to cost somewhat less” than the Trans Mountain Pipeline expansion.

The Greens have vowed to scrap the expansion and put that money toward the project.

Upgrading the electric grid to 100 per cent sustainable energy would also be a cost-effective, long-term solution, the Greens believe, though critics say Ottawa is making electricity more expensive for Albertans amid the transition.

“Current projects for renewable energy in Canada and worldwide are consistently at lower capital and operating costs than any type of fossil, hydro or nuclear energy project,” the party spokesperson said.

The party’s platform includes other potential sources of money, including closing tax loopholes for the wealthy, cracking down on offshore tax dodging and a new corporate tax on e-commerce companies, such as Facebook, Amazon and Netflix. The Greens have also vowed to eliminate all fossil fuel subsidies.

As for the economic realities, Katz-Rosene acknowledged that May’s plan may appeal to “radical” voters who view economic growth as anathema to addressing climate change.

But while May’s plan would be disruptive, it isn’t anti-capitalist, he said.

“It’s restrained capitalism. But it by no means an anti-capitalist platform, and none of the parties have an anti-capitalist platform by any stretch of the imagination,” Katz-Rosene said.

From an economist’s perspective, Bernard said the plan is still “very costly” and that taxes can only go so far.

“In the end, no corporation operates at a loss. At some stage, these taxes have to go to the users,” he said.

But conversations around money must also consider the cost of inaction on climate change, Hudema said.

“Costing (Elizabeth May) is always a concern and how we’re going to afford these things is something we definitely need to keep top of mind. But within that conversation we need to look at what is the cost of not doing what is in line with what the science is saying. I would say that cost is much more substantial.”

“The forecast, if we don’t act – it’s astronomical.”

Closure of 3 Southern California power plants likely to be postponed

California Gas Plant Extensions keep Ormond Beach, AES Alamitos, and Huntington Beach on standby for grid reliability during heat waves, as regulators balance renewables, battery storage, and power, pending State Water Resources Control Board approval.

 

Key Points

State plan extending three coastal gas plants to 2026, adding capacity as California expands renewables and storage.

✅ Extends Ormond Beach, AES Alamitos, AES Huntington Beach

✅ Mitigates blackout risk during extreme heat and peak demand

✅ Pending State Water Resources Control Board approval

 

Temperatures in many California cities are cooling down this week, but a debate is simmering on how to generate enough electricity to power the state through extreme weather events while transitioning away from a reliance on fossil fuels as clean energy progress indicates statewide.

The California Energy Commission voted Wednesday to extend the life of three gas power plants along the state’s southern coast through 2026, even as natural-gas electricity records persist nationwide, postponing a shutoff deadline previously set for the end of this year. The vote would keep the decades-old facilities _ Ormond Beach Generating Station, AES Alamitos and AES Huntington Beach — open so they can run during emergencies.

The state is at a greater risk of blackouts during major events when many Californians simultaneously crank up their air conditioning, such as a blistering heat wave, illustrated by widespread utility shutoffs in recent years.

“We need to move faster in incorporating renewable energy. We need to move faster at incorporating battery storage. We need to build out chargers faster,” commissioner Patricia Monahan said amid an ongoing debate over the classification of nuclear power in California. “We’re working with all the energy institutions to do that, but we are not there yet.”

The plan, put together by the state’s Department of Water Resources, still needs final approval from the State Water Resources Control Board, which may vote on the issue next week. Democratic Gov. Gavin Newsom signed legislation last year creating an energy reserve the state could use as a last resort if there is likely to be an energy shortage, a challenge mirrored by Ontario electricity shortfall concerns elsewhere. The law allowed the Department of Water Resources to fund or secure power sources in those instances, after PG&E shutdown reasons drew attention to grid vulnerabilities.

The commission acknowledged it was a difficult decision. Environmentalists say the state needs to transition to more short- and long-term solutions that will help it move away from fossil fuels and to rely more on renewable energy sources like solar and wind, similar to Ontario's clean power push in recent years. They’re also concerned about the health impacts associated with pollution from gas plants.

Rooftop Solar Grids

Rooftop solar grids transform urban infrastructure with distributed generation, photovoltaic panels, smart grid integration and energy storage, cutting greenhouse gas emissions, lowering utility costs, enabling net metering and community solar for low-carbon energy systems.

 

Key Points

Rooftop solar grids are PV systems on buildings that generate power, cut emissions, and enable smart grid integration.

✅ Lowers utility bills via net metering and demand offset

✅ Reduces greenhouse gases and urban air pollution

✅ Enables resiliency with storage, smart inverters, and microgrids

 

As urban areas expand and the climate crisis intensifies, cities are seeking innovative ways to integrate renewable energy sources into their infrastructure. One such solution gaining traction is the installation of rooftop solar grids. A recent CBC News article highlights the significant impact of these solar systems on urban environments, showcasing their benefits and the challenges they present.

Harnessing Unused Space for Sustainable Energy

Rooftop solar panels are revolutionizing how cities approach energy consumption and environmental sustainability. By utilizing the often-overlooked space on rooftops, these systems provide a practical solution for generating renewable energy in densely populated areas. The CBC article emphasizes that this approach not only makes efficient use of available space but also contributes to reducing a city's reliance on non-renewable energy sources.

The ability to generate clean energy directly from buildings helps decrease greenhouse gas emissions and, as scientists work to improve solar and wind power, promotes a shift towards a more sustainable energy model. Solar panels absorb sunlight and convert it into electricity, reducing the need for fossil fuels and lowering overall carbon footprints. This transition is crucial as cities grapple with rising temperatures and air pollution.

Economic and Environmental Advantages

The economic benefits of rooftop solar grids are considerable. For homeowners and businesses, installing solar panels can lead to substantial savings on electricity bills. The initial investment in solar technology is often balanced by long-term energy savings and financial incentives, such as tax credits or rebates, and evidence that solar is cheaper than grid electricity in Chinese cities further illustrates the trend toward affordability. According to the CBC report, these financial benefits make solar energy a compelling option for many urban residents and enterprises.

Environmentally, the advantages are equally compelling. Solar energy is a renewable and clean resource, and increasing the number of rooftop solar installations can play a pivotal role in meeting local and national renewable energy targets, as illustrated when New York met its solar goals early in a recent milestone. The reduction in greenhouse gas emissions from fossil fuel energy sources directly contributes to mitigating climate change and improving air quality.

Challenges in Widespread Adoption

Despite the clear benefits, the adoption of rooftop solar grids is not without its challenges. One of the primary hurdles is the upfront cost of installation. While prices for solar panels have decreased over time, the initial financial outlay remains a barrier for some property owners, and regions like Alberta have faced solar expansion challenges that highlight these constraints. Additionally, the effectiveness of solar panels can vary based on factors such as geographic location, roof orientation, and local weather patterns.

The CBC article also highlights the importance of supportive infrastructure and policies for the success of rooftop solar grids. Cities need to invest in modernizing their energy grids to accommodate the influx of solar-generated electricity, and, in the U.S., record clean energy purchases by Southeast cities have signaled growing institutional demand. Furthermore, policies and regulations must support solar adoption, including issues related to net metering, which allows solar panel owners to sell excess energy back to the grid.

Innovative Solutions and Future Prospects

The future of rooftop solar grids looks promising, thanks to ongoing technological advancements. Innovations in photovoltaic cells and energy storage solutions are expected to enhance the efficiency and affordability of solar systems. The development of smart grid technology and advanced energy management systems, including peer-to-peer energy sharing, will also play a critical role in integrating solar power into urban infrastructures.

The CBC report also mentions the rise of community solar projects as a significant development. These projects allow multiple households or businesses to share a single solar installation, making solar energy more accessible to those who may not have suitable rooftops for solar panels. This model expands the reach of solar technology and fosters greater community engagement in renewable energy initiatives.

Conclusion

Rooftop solar grids are emerging as a key element in the transition to sustainable urban energy systems. By leveraging unused rooftop space, cities can harness clean, renewable energy, reduce greenhouse gas emissions, and, as developers learn that more energy sources make better projects, achieve long-term economic savings. While there are challenges to overcome, such as initial costs and regulatory hurdles, the benefits of rooftop solar grids make them a crucial component of the future energy landscape. As technology advances and policies evolve, rooftop solar grids will play an increasingly vital role in shaping greener, more resilient urban environments.
